Uncovering the potential MTAs, candidate genes and microRNAs regulatory networks involved in salinity stress tolerance triggered in Iranian Aegilops tauschii.

ABSTRACT: This study evaluated the molecular diversity and identified marker-trait associations (MTAs), candidate genes, and microRNAs (miRNAs) regulatory networks in Iranian Aegilops tauschii ecotypes under salinity stress during the seedling stage. The results demonstrated that ISJ9 exhibited the highest values for polymorphic information content (PIC), effective number of alleles (Ne), gene diversity (h), Shannon's information index (I). Similarly, OPE03-Xgwm44-7DF displayed the highest Ne and I values. Therefore, ISJ9 and OPE03-Xgwm44-7DF markers demonstrated the greatest discriminatory power for distinguishing Aegilops tauschii ecotypes. Association analysis under salinity stress identified 115 MTAs, including iPBS44-D and OPB01-Xgwm44-7DR-3. Subsequent bioinformatics analyses revealed 254 cand
